In the spirit of saving readers from watching bad shows, here are lengthy quotes from Hanners:

Anyhow, this final episode takes us to a final battle between animals (or rather, humans turned into animals) and humans, and as a result Momoko versus Ran and Midori - A battle that the latter pair eventually triumph over by not fighting at all, which somehow convinces those animals to become humans again. [...]

In its entirety, there were a few things wrong with Telepathy Shoujo Ran. Firstly, it proved to be an incredibly formulaic series, which works fine for so long but after twenty-six episodes.... well, it leads to people calling it the dullest anime of 2008. Perhaps equally damaging was the way the telepathy angle of this show was abused, with Ran and Midori's powers soon becoming some kind of catch all to help them out of any situation, which extended to levitation, force fields and goodness knows what else. What the main protagnosists of a series can pull something out of nowhere to save them in any given situation, things soon get... you guessed it... dull, as any kind of drama and tension is lost.

Myself, I am especially sensitive to anything arjunesque, so Ran moves to the "Rejects" pile with extreme prejustice.

UPDATE: I think Red Comet #3 is somewhat more positive, as much as I can ascertain:

テンポものりも良く、シリアスになりかけても翠が上手く場を盛り上げてくれたおかげで楽しく見れたように思う。

(翠 is apparently Midori: the third spelling by now!)
